Borrowed from Latin -ēnus, from Ancient Greek -ηνός (-ēnós), forming adjectives from place names.
-ene (adjective-forming suffix, not comparable)
Borrowed from French -ène, chosen by French chemist Jean-Baptiste Dumas to avoid confusion with chemicals in -ine.
-ene (noun-forming suffix, plural -enes)
The common names of some other organic compounds also end in -ene.
-ene
From 古期英語 -ena, for earlier -ana, from Proto-West Germanic *-anō, *-ōnō, from Proto-Germanic *-anǫ̂, *-ōnǫ̂, from the Proto-Indo-European genitive plural suffix *-oHom when attached to n-stems.
-ene
Inherited from 古期英語 -enne, -anne (with reduction of the geminate unstressed position), from Proto-West Germanic *-annjē, *-jannjē, *-ōnnjē, possibly equivalent to -en (uninflected infinitive) + -e (dative singular).

The suffix -ene is used in organic chemistry to form names of organic compounds where the -C=C- group has been attributed the highest priority according to the rules of organic nomenclature. Sometimes a number between hyphens is inserted before it to say that the double bond is between that atom and the atom with the next number up. This suffix is taken from the end of the word ethylene, which is the simplest alkene. The final "-e" disappears if it is followed by a suffix that starts with a vowel, e.g. "-enal" which is a compound that contains both a -C=C- bond and an aldehyde functional group. If the other suffix starts with a consonant, the final "-e" remains, e.g. "-enediyne" (which has the "-ene" suffix and also the "-yne" suffix, for a compound with a double bond and two triple bonds.)
